Abstract
An automatic speed control device for a vehicle includes a distance measuring sensor,a vehicle speed sensor,and a control unit,for controlling the vehicle speed. In the control unit,a target speed determining section,determines a target speed corresponding to a distance detected by the distance measuring sensor,and the vehicle speed detected by the vehicle speed sensor,A speed storing section,of the control unit,stores the detected vehicle speed as a set speed. A selecting section,of the control unit,selects a smaller speed of the target speed and the set speed. A speed control section,of the control unit,controls the vehicle speed so as to be the smaller speed selected by the selecting section,When losing the preceding vehicle, the speed control section,further controls the vehicle speed so as to maintain a present vehicle speed until the driver's vehicle reaches a lost point where the preceding vehicle was lost.
